ABSTRACT: In the paper, we show and discuss upon first results of research project
with title Behaviour of Fibre Reinforced Shotcrete (FRS) Right After Construction.
The results obtained on research field of primary lining of Dekani tunnel represent the
starting-point of the project. The test method proposed by RILEM technical
committee TC 148-SSC was used for evaluation of behaviour of young FRS. First
obtained results of the research project show that added fibres have significant
influence over behaviour of young FRS up to the age of 8 hours. We ascertain that the
compressive strength of young FRS increases as well, besides ductility.
